Claims. (Cl. 137-628).

My invention relates to 'a uid control regulating valve and is a'continuation in part, ,and division of,rny former patent application SerialNumber 69,350, filed lJanuary .5, 1949,'now Reissue Patent No. 23,342, and is especially adapted for. use therewith.'

The object of my invention `is to produce a vdivided uid regulating valve that will function for adjoining dual port openings, either jointly or severally, and by single operating mechanism.

Another object is to produce a dual port 'regulating valve that may be .mechanically operated for one-port, and automatically operated for the adjoining ,.port,A and for chosen predetermined positions;

A further. object is toprovide a divided spring valve for opening adjoining kports simultaneously at predetermined sections, and automatically release andA close one valve section .at any chosen'predetermined position,` and without effecting the opposite valve operation.

A still lfurther object is to producel a divided .spring valve for dual port regulation, that is simplek in construction,.easily and efficiently operated and thatcan be manu-- factured at a verylow cost.

These several objects are attained in the preferred form by the construction and arrangement of parts as are more fully hereinafter set forth.'

Similar parts on all drawings `are marked by similar numerals or letters.

The dual valve is especially for controlling the iluid intake flow entering a connected gear uid transmission unit as illustrated/in my prior-patent mentioned, the

outer port 16 leading from the transmission-reserve iluid storage chamber, y.for instant: refillingy therefrom when starting operation, then closing;` while they mner port channel 41 remains open for continued internal recircu lation through the connected gear transmission unit until later closed by operator.

I will now describe more fully the detailed construction of my divided dual port valve, referring to the drawings and the marksthereon.

As herein illustrated, they outer `flanged valve 44 is mounted over .the external `channel 'port 16,1wl1ilefftheinner Wing valve section '44a' is positioned to engage and operate the internal` channel port 41, both valve sections being pivoted. together and; rotatably mounted overa common pivot shaft 1 fXedly mounted on the outer -wall of a control casing A. andadjacent to theexternal portl 16, as is illustrated in the Fig.v 1V of the drawings.

The inner wing valve section- 44a is formed of a at arm plate a, having a turned bearing hub b 1iXedly'pro-= jected from one end thereof, at right angles thereto, Esaid hub having a concentric shaft bearing therethrough forv rotatably mounting on the=pivot shaft 1, the arm .plate being also. designed .with acurved Awing valve plate cv projected from the opposite plate end positioned to en= gage and t the casing'internaLchannel port '41. The

outer valvesection44 is formedlas an elongated flanged recess plate with oval ends, and with a circular bearing dl throught one end thereof, concentric with the oval end flange and designed for rotatably mounting vover the inner valve plate bearing hub b and inclosing both said inner valve section44a.- and `the casing exterior `charme]- port 16. Thevalve flanged edge e is milled to a true surface for forming a perfect pressure joint with'the port 16 outer wall surface, and is retained in contact therewith by a suitable plate valve slide 5, designed andvv mounted to inclosetthevalveanged edges when in its closed position, and isrigidly retained on lthe casing walls by screws 6, or other suitable means, allowing yboth valve sections to rotate Von the. common pivot shaft 1 .for complete valve operation,.either jointly or severally, and asillustrated in the Figs. l and 7 of the drawings. The plate valve slide may be extended, vif desired, .to encircle the entire valve flanged edge. when high-fluid back pressure may require more rigid valve'support. The valve section 44 is retained in its closed position, when unrestrained, by the stressed exterior spring 2 as mounted onthe casing A wall, and the interior valve section 44a is retained in its closed position, whenunrestrained, by the stressed intervening spring 3 as mounted between the recessed valve section edges, and as illustrated in the Fig., 3 of the drawings., Mounted overzthe'inner valve section bearing hub .b is a rocker arm 4,.splined to the hub section .by Ythe key 7 movable sidewise in an'enlarged keywayS, designedrfor rotating andopeningthe inner. valve section .44a Whenoperating pressurev is applied thereto through the tconnectingoperating, rod 45', non mally when applied/.to an automobile :fluidv driveand control unit casing, `Would bethe foot operatingxpedal,

arm end f engages the opposite port channel wall and releases same from the ratchet recess 11, automatically allowing the outer valve section 44 to close over port 16 by reaction of the stressed closing spring 2. The length of the ratchet arm f may be varied, as desired, as indicated by dotted line, in Fig. 3, for timed releasing the outer valve section 44 at any predetermined position during the opening stroke. The exterior Valve spring 2 must be stronger than the interior valve spring 3 to insure the full closing of both valve sections. When high back pressure is involved within the casing channel circuits, the inner wing valve section 44a may require special valve locking means, and a dual lock-release ratchet 13 is pivotally mounted on the anged head g of the pivot shaft 1, by the pivot bearing pin 14, designed and positioned within the pin head recess h, with the lock ratchet arm k engaged within the valve hub b tooth recess 15 for the valve closed position, thus rigidly restraining any valve 44a movement when so locked. The opposite release ratchet arm m being positioned to engage an adjacent lifting cam 26 Xedly mounted on the rocker arm hub 4, designed for the free splined arm movement within the key recess 8, for lifting the lock-release ratchet clear from the hub tooth recess 15 before the valve rotation is commenced by the engaging key 7. The lock-release ratchet is restrained in its closed position by an engaging stressed spring 17 mounted thereon, or by any other suitable means.

When low casing uid pressure is involved, the lockrelease ratchet 13 may be omitted, and the rocker arm 4 Xedly keyed directly to the inner valve section bearing hub b, and without the extended keyway 8, and as illustrated in the Figs. 8 and 9 of the drawings. The dual valve operation is exactly the same as in the former case, and the valve sections are securely retained in their closed positions by reaction of the operating rod spring 9.

It is pointed out that both the ratchet and the spring means as herein disclosed, are illustrative of any suitable substitute type of spring, or engaging units, as may be substituted therefor, also the valve drive ratchet 10 may be substituted for suitable locking or driving units, such as a pivoted lock bar 18 also operated from the lift cam 26, or similar units as desired, as indicated by the dotted lines in the Fig. 5.
